In 2022, Yongchun Elementary School and Yongji Elementary School will merge into a new school - Shuangyong Elementary School. The original school buildings of the two schools will soon be demolished and rebuilt. The construction of public art on campus is one of the important constructions of the future new school building. Through this opportunity, students have the chance to participate in the construction of public art, and we hope that the public art of the new school building in the future can be combined with students' ideas and completed together with artists. The concept of this course is to stimulate students to think about how to practice and participate in artistic creation in a larger social context through public art; students can think from the perspective of others and propose solutions; and challenge students to complete tasks together through collaborative learning.
